Al PowerBook 1GHz - 4 Beeps at Startup - is it Fixable ?

i've got a Al PowerBook G4 1GHz, when i press the power button it will beep 4 times (and flash 5 times) - this should be a faulty boot rom - is thera any way to fix this?
i have some technical knowledge, repaired many cell phones (hardware and software issues), also did some logicboard repairs on imacs and macbooks
would be nice to save this great looking piece of technic

HI and Welcome to Apple Discussions...
should be a faulty boot rom
According to this link you are correct: Power On Self-Test Beep Definition - Part 2
According to that link contacting an Apple certified provider or taking it into an Apple store is probably your best bet.

Totally agree. PBG4 is a workhorse.

IMac G4 Flat Panel 1Ghz - 1 beep when turning it on.

I have an iMac G4 Flat Panel 1Ghz that beeps once when you turn it on. After doing some research, I learned the 1 beep could be no RAM or RAM problem. I replaced both the internal RAM and the easily accessible RAM with RAM from a reputable dealer that markets this RAM just for iMac G4s. I still get one beep after startup. I tried taking one stick out and all variations of using the old and new RAM with no difference. I did more research that maybe it was the power supply. By the way, originally this iMac was shocked through its Ethernet port with lightning. I since bought a new motherboard, new RAM as stated, and now also the power supply. After putting it all together, I still get one beep at startup. I have reset the PMU also. Also added a new battery. Looking forward to your suggestions.

There may be some indication of the beep's cause after some thorough
testing of the computer with some utility software; perhaps even the basic
Apple Hardware Test which would have accompanied the computer when
new could be helpful to some degree, if the machine were run in that, in a
long continuous loop to see if at some point, it may generate some codes.
However, the startup sequence itself is where such a hopeful bit of information
would more likely be generated; and this is the kicker, in that some of the info
at start-up is too early in the beginning of the run-cycle to be recorded or read.
But, you may find evidence of the issue in the Console error message reports
in that utility; and there are a few different sub-titles of places in Console to look.
Also, you may be able to find some error or crash messages, or other runtime
messages and glitches, in the System Profiler> Software> progression path.
There may be another source of the single-beep on startup tone. Not sure of
any other, though; since the Power-on self-test is generally what checks out
those computers on start-up. And the 'single beep' suggests there is a RAM
issue, as this Beep would replace the normal startup chime.
So, that early in the startup, and without a booted system, the error logs or
crash and failure reports would not be generated to be read later.
Is the computer you have really a 20" LCD and does it truly have a 1GHz
CPU? Or, does it have a 1.25GHz PPC processor, as it should? Did the
company you obtained the replacement logic board from, have anything
to say about the kinds of issues you've noted the computer displaying?
There may have been a limited duration warranty on the rebuilt board.
There have been a few of the old iMac G4 17" & 20" 1.25GHz models
generating an odd, single 'buzz' sound after the normal startup tone.
Is your's making a 'single beep' or a 'buzz' sometime after booting?
Do you have any other RAM chips of correct supported version to
replace one or both RAM slots, of reliable quality product? How was
the OS installed into the computer, or have you been unable to do so?
Once in a great while, new correct RAM could be bad on arrival. Rare.
{This is a lot like chasing gremlins or setting a trapline for gnomes.}
Maybe someone, such as the contributor alias 'spudnutty' may know of
some other factor in this matter that he has found, that may cause that.
Good luck & happy computing!

Correct power adapter for PowerBook 1ghz Titanium?

Could someone please confirm which power adapter is the correct one for use with a Titanium PowerBook 1ghz, as would have been shipped with the PowerBook from Apple?
I've been searching and have found a number of model numbers ie M8743LL/A, A1021, 661-3746 and 661-3346....
Which is the same one as would have shipped from Apple with the PowerBook 1ghz Ti?
Im in Europe, UK if that matters to the model number?

OK, I have a unit with A1021 on it. I recall that one could get the international plug set as an accessory and just replace the little clip-on adapter, but the unit itself remained the same model number. If you have the clip-on plug or cord assembly already for UK plugs, then the A1021 should work fine.
This might help, as well:

Dx2300, beep on startup

I bought a DX2300 microtower used. It worked beautifully at the sellers house. We removed the wires/cables and I took it home. When I reassembled everything I got no action on the monitors(dual), no lghts on the wireless keyboard nor mouse. The CPU makes a single, long beeping on startup. The only thing I did to it was clean out the dust from the front vents and fan units. I believe the seller had a 1T byte external harddrive, but other than that, II believe it's all the same. Any suggestions?
This question was solved.
View Solution.

I went inside and unplugged and reset each cable I could. It started up smooth and other than the black screen telling me it hadn't been shup down correctly - all works fine. I was able to get my wireless internet set up. All is well in my world. Thank you very much for the help.

3 beeps at startup

What does three beeps at startup mean???

It usually means the machine can't detect any RAM. Try reseating the RAM modules (directions are in the users guide that came with the machine).

G4 beeps on startup

I got a new HD and new 512MB stick of ram put into my G4. It seemed fine after the HD was installed but a few days later when I bought some second hand ram and slapped it in I got a faint beep on startup. I tried every combination of the ram, but couldn't get rid of the beep untill I unplugged the new HD. So I took it in to the Mac store where I got the HD installed and we couldn't hear the beep!! Took it home and it beeps again, but only when the new HD is plugged in. One strange thing is that the total ram only shows up as 1.19 when it should add up to 1216 MBs; that is two 512's, one 128, and one 64mb stick.
Any ideas?

Hi, Mike -
Welcome to Apple's Discussions.
One strange thing is that the total ram only shows up as 1.19 when it should add up to 1216 MBs; that is two 512's, one 128, and one 64mb stick.
1216MB is correct, and 1.19GB is correct. RAM math is a bit odd because it is base2. One GB = 1024MB, not 1000MB. So, 1216MB divided by 1024MB/GB yields 1.19GB.
Is it possible the drive itself is beeping? Some few have been known to do that, but when that happens it usually presages a drive failure - not something expected with a new drive.
Is the drive jumpered correctly? If your Mac is older than a G4 (MDD) model, you should not use Cable Select jumper settings.
There are some beeps at startup which can indicate RAM issues -
http://docs.info.apple.com/article.html?artnum=58442
However, those will replace the normal startup chime. That is, if you hear the normal startup chime and then the beeps, it's not a RAM issue.
At least one person posted a similar issue a few years ago. Careful listening finally traced it to the user's UPS - it was alerting that it was running on battery.

My Emac just beeps at startup

My niece was using my Emac the other day and she said that all of a sudden it just shut down. When we tried to reboot it, all it does is beep at startup (about 20 times) and then it has the little folder on the screen that alternates between the question mark and a face. When I tried to boot off of the install disk it does boot up, but wont let me re-install the osX. It wont give me the hard drive as a option to install to. I went to the system profiler and it does show that the hard drive is there, but obviously something is wrong. Not really sure what to do and any help would be appreciated.

Welcome to Apple Discussions, bleachfix.
When you boot up from the OS X install disc, select Disk Utility from the utilities menu. What does it have to say about your hard drive?

3 short beeps on Startup

I had to do a System Recovery and ever since then, I get 3 short beeps on startup. It does it 4 times... Any ideas?

Hi,
Could be BIOS related..
The link below will tell you what the Beep codes indicate..Follow the instructions as per the the beep codes
Beep and LED code descriptions
BIOS Beep Codes
Note:
If you have HP Support Assistant installed on the computer(The Blue Question Mark) then open it ==> Complete all pending Updates & Tuneups==> Restart and Check. It may solve your problem
Although I am an HP employee, I am speaking for myself and not for HP.

Three loud beeps on startup

I have been experiencing three loud beeps on startup with my Macbook Pro.
Aftter the beeps, the computer stays on a blank screen until I force a shutdown and restart, sometimes taking 3 tries to get past the beeps. Otherwise, It runs great, never crashes or locks up.
I tried reseating the RAM (2-1 gig dimms) after someone told me they thought that the distinctive 3-beep warning was a "bad ram" message. That did not make a difference.
Does anyone know what this may mean?
Thanks,
Dave Kowalski

2nd that - first check the ram is firmly seated - sometimes it's not all the way in the slots..

Best of luck.

T500 Beeping on Startup

One week ago, my computer (Lenovo ThinkPad T500) has started beeping upon startup (one long, two short) and will not allow the system to start. I have to shut down and restart a considerable amount of times before the display finally shows up. The odd thing is that it has informed me that this indicates a video problem, and yet I have run diagnostics and the such, and there is nothing wrong. Furthermore, my computer runs perfectly, if not even better than before the beeps started.
This problem is starting to get annoying and I'm afraid that I might irreversibly damage my computer if I keep trying to start it up when it is beeping. How can I fix this?
Thanks for all of your help!
Solved!
Go to Solution.

katrimc, welcome to the forum
according to the Hardware Maintainance Manual, (pdf p. 52), the beep code means that you possibly have a problem with either your System Board, Display or Memory. I suggest removing and reseating your memory, (pdf p. 78 or look here), and if the problem persists to run memtest86 to check your memory. Let it make at least 3 full passes.
If your memory passes and the symptoms still persist you should call support.
Let the forum know how you get on.

Mac powerbook g4 15" Auminum, on startup has a black screen and no signal to external monitor

Powerbook G4 1.5 Ghz 15" Aluminum
After watching a dvd, I turned the laptop off and closed the lid before the screen was completely dark. I also forgot to take the dvd out. The next day I get a start up chime and a black screen. Will not work with external monitor. Will not let me do pram reset as I couldn't see the picture anyway. Hard drive appears to be fine. I tried swapping the two ram modules. Took the lower one out and still no results. My main question is, before I just geek out and put a new logic board in, what are the possible loose connection (cables) causes?

This issue is not unfamiliar among PowerPC G4 users, in desktop or portable models.
The cause may vary and so when looking through incidents of a similar nature, try to
be patient and get past duplicate-sounding experiences as referenced by the sources.
There are more than a few in this search thread that sound like your situation:
https://www.google.com/?gws_rd=ssl#q=powerbook+g4+black+screen+on+startup
Depending on the PowerBook model, some have clock battery/capacitor on logic board
that once it fails, there can be startup issues as a result... So that's one to check. And
then there are the connections that may have come loose on the logic board, over years
of handling and small movement, these could finally have failed to contact finally. Or the
DC-in Board may have chosen to fail, so power may be unable to get past a circuit.
Troubleshooting based on a few symptoms can be... troublesome, tedious; or costly.
The iFixit.com guides have sections where people asked questions, such as:
https://www.ifixit.com/Answers/View/131619/PowerBook+g4+has+startup+chime+no+ima ge
The keyboard shortcuts to attempt to force a computer to start may be of no avail if
the hardware has defects, or if wires have come off their necessary junctions inside.
If you have time and some money, companies who specialize in repairing Apple
portable computers could restore its function & warranty their work. wegenermedia
is worth contacting if the computer is one you want to keep around while. They did
a repair for me on one of my Apple portables, and I'd probably go that route again.
So, anyway, if the unit uses a clock or PRAM battery, it may need replacement.
Or in another direction, issue could be a power related circuit failure; or worse.
There are graphic display components that fail at a point where an external &
internal display both won't light up. These are mapped out in iFixit guides or in
others online, depending on the model G4 PowerBook they show.
Good luck & happy computing!

New Macbook Pro beeping on startup + showing progress bar

Hi;
Yesterday I bought my new 13inch MacBook Pro. When I came to turn it on this morning, it first made a beep sound; then it showed the Apple logo with a progress bar under it. The bar made no progress, suddenly it rebooted again but without making any sound, and the Apple logo re-showed again with the bar. This happeded 3 times before the Mac booted.
Any ideas?
Please help, I am new to Mac, and I'm Lovin' It.
Thank you.
Elias.

It is true; the past day I had updated my software and I turned it off. This all started happening the next day. I understand that it might be updating the EFI firmware, I remember I did install it; but the problem is that it happened twice in a row (I shut down the computer and re-turned it on again) and the same things happened. But it never happened again. I just wanted to know that my new MB is OK. (I am new to Mac and not familiar with MB beeping at startup, is it normal?).
Thank you.
If the issue got fixed that means that the MacBook was updating its EFI. The "bong" sound is normal at start up, however the "beep" sound will be heard only when the EFI is update or has a problem.

Mid 2010 MacBook pro gray screen beeps no startup

Hello,
My mid 2010 MacBook pro will not startup. What I get is the startup chimes with white or gray screen. Then some beeping and clicking starts. Will not boot remotely from FireWire drive.
I'm thinking it might be ram based on what I have read so far as opposed to a hard drive crash.
Any ideas?

The number of beeps should tell you what the problem is.

2011 Macbook pro upgrade to 16gb RAM -- 3 beeps on startup

My macbook pro is a 15" 2.2ghz quad i7 model purchased June of 2011. I read and researched everywhere and found that this model could support 16gb of RAM so I ordered this, Corsair 16GB Dual Channel DDR3 SODIMM. When I installed the ram and attempted startup I just got a black screen and 3 consecutive beeps and then learned this is a problem directly related to the ram installed. I installed the old ram (4gb) and that is how I'm typing this. Why would this happend if it proved so successful for so many others, according to amazon. Do I need to revert back to snow leopard? Any advice will help thanks.

it is actually that simple since i ran into the same problem when i went 16GB on my mbp.
heard it click but on both banks, turn the computer on and nothing 3 beeps.
took the ram out, put it back in straight, looked at both notches and make sure it's aligned then click again.
turned it on, and i'm back in business.
quick question, what speed did you get?
